Accenture report shows 90% of firms remain vulnerable to AI-driven cyberattacks in 2025

A vast majority of large enterprises remain unprepared to defend against next-generation cyber threats accelerated by artificial intelligence, according to Accenture’s latest State of Cybersecurity Resilience 2025 report. The study, based on a survey of 2,286 cybersecurity and technology leaders across 17 countries and 24 sectors, warns that only 10% of organizations globally have achieved what Accenture defines as the “Reinvention-Ready Zone”—a state of mature cybersecurity strategy and technical capability required to secure AI-driven transformation.

Accenture plc (NYSE: ACN) said the gap between AI innovation and security preparedness is now a major operational risk, especially as generative AI tools lower the barrier for sophisticated cyberattacks. The firm emphasized that 63% of respondents currently fall into the “Exposed Zone,” lacking both a strategic cybersecurity roadmap and the infrastructure resilience necessary to mitigate AI-powered threats. The remaining 27% occupy a transitional space known as the “Progressing Zone,” reflecting partial but insufficient capability.

The findings underscore a fundamental issue: as enterprises rush to adopt generative AI, they are not investing proportionally in security measures, exposing critical data pipelines, supply chains, and cloud environments to exploitation.

Why are most organizations struggling to secure their AI systems despite rising cyberattack volumes?

The disconnect between AI deployment and cybersecurity readiness appears to be widening. Accenture found that 77% of surveyed firms do not have the foundational AI and data security protocols needed to safeguard large language models, generative AI systems, or their associated data assets. Only 28% of organizations embed security into their transformation initiatives from the start, which experts say is a key differentiator in protecting against adversarial AI use cases.

At the same time, the number of cyber incidents continues to surge. In the third quarter of 2024 alone, enterprises faced an average of 1,876 cyberattacks—representing a 75% year-on-year increase. This wave of attacks includes more sophisticated threats such as AI worms like “Morris II,” which can autonomously manipulate LLMs to extract sensitive information without human oversight. These risks are compounded by the growing use of deepfakes, with documented cases involving fraudulent voice clones impersonating government officials to solicit wire transfers of over €1 million.

Institutional investors are reportedly concerned that this rising threat level, coupled with underinvestment in AI security, could erode stakeholder trust and increase long-term compliance costs. Analysts believe that unless organizations pivot quickly, reputational damage and business continuity risks will mount.

How does the cybersecurity maturity gap impact operational resilience and financial performance?

Accenture’s report divides cybersecurity maturity into two core dimensions: cyber strategy and cyber capability. Only 34% of organizations demonstrate strength in designing cyber strategies, and just 13% have implemented the technical infrastructure needed to detect and respond to modern AI threats.

The Reinvention-Ready cohort—roughly 10% of surveyed firms—demonstrate mature, adaptive, and continuously evolving security postures. These organizations are 69% less likely to suffer advanced AI-powered attacks and are 1.5 times more effective in blocking threats. They also report 1.6 times higher ROI from their generative AI investments, 1.7 times reduction in technical debt, and a 15% uplift in customer trust metrics.

In contrast, enterprises in the Exposed Zone experience the slowest detection and remediation speeds and the weakest visibility across their digital infrastructure. These firms are also more likely to face breaches of operational technology systems and violations of emerging AI governance standards.

Accenture’s economic modeling suggests that a 10% targeted increase in cybersecurity investment focused on Reinvention-Ready practices can improve threat detection and containment efficiency by 14%.

What four strategic actions did Accenture recommend to achieve AI cybersecurity resilience by 2025?

To bridge the gap and future-proof AI investments, Accenture recommended four critical actions. First, enterprises must develop and deploy a purpose-built governance framework that aligns cybersecurity with regulatory mandates and embeds accountability at the board level. Despite widespread AI adoption, only 22% of companies surveyed have implemented clear policies and training on generative AI use.

Second, digital systems must be designed to be AI-secure from inception. This includes embedding security protocols directly into AI development and deployment workflows, yet only 37% of organizations currently assess AI tool security before going live.

Third, enterprises must maintain resilient AI systems through proactive threat detection, independent validation, and continuous model testing. This includes red team exercises, real-time anomaly monitoring, and runtime protection against adversarial input manipulation.

Fourth, organizations are encouraged to reinvent cybersecurity itself through AI. With an estimated 4.8 million unfilled roles in global cybersecurity, AI-powered automation is positioned as a way to augment analyst capacity, detect threats faster, and orchestrate security workflows more effectively.

Why is the cybersecurity talent shortage compounding AI risk exposure in enterprise environments?

Eighty-three percent of executives cited workforce limitations as a major barrier to strengthening their cyber defenses. Accenture’s report notes that spending on generative AI outpaced security allocations by a ratio of 1.6 to 1 in 2024 and is projected to rise to 2.6 to 1 in 2025. This widening imbalance reflects a strategic misalignment that analysts warn could delay necessary security upgrades and increase post-breach remediation costs.

The talent gap is particularly acute in AI security roles, where niche skills such as adversarial prompt detection, LLM monitoring, and secure MLOps integration are in short supply. Organizations in the Reinvention-Ready Zone are reportedly ahead in training programs, AI-specific security certifications, and incident simulation drills.

Those lagging behind often struggle to build resilient security teams, leaving them dependent on fragmented third-party tools and vulnerable to attack vectors like data poisoning, model inversion, and prompt injection attacks.

How are organizations using AI to automate and strengthen cybersecurity operations today?

Accenture highlighted that 71% of common cybersecurity analyst tasks can now be automated through generative AI. This includes anomaly detection, log triage, alert correlation, case enrichment, and even risk scoring.

Reinvention-Ready firms are embedding AI security agents into their SOC (Security Operations Center) workflows, enabling real-time decision-making and risk mitigation. For example, some use AI assistants to summarize threats, prioritize incidents, and conduct root-cause analysis—improving incident response times while alleviating analyst burnout.

The report also emphasized the potential of AI-powered identity and access management (IAM) systems to support Zero Trust policies. These systems use behavioral biometrics and contextual risk scoring to dynamically assign access privileges, reducing human error and improving compliance posture across hybrid and multicloud environments.

What are institutional investors and boards expected to prioritize based on these cybersecurity findings?

Institutional stakeholders are expected to place greater pressure on executive leadership to address cybersecurity as a strategic risk. Accenture urged companies to elevate AI security to a board-level conversation, integrate performance metrics into digital KPIs, and align cybersecurity strategy with overall business transformation.

Experts believe investors will increasingly differentiate between AI leaders that are secure-by-design and those that treat security as a retrofit. Reinvention-Ready firms are likely to attract long-term capital due to their resilience, lower breach costs, and enhanced customer trust.

Accenture’s report concluded that cybersecurity is no longer a back-office compliance function—it is a frontline business enabler that must evolve in tandem with the AI landscape.
